Occassionally we see an error related to polling starting an job though there should be no new baselines on ClearCase components configured.

In the following example we use two components. There are baselines model-1, model-2, model-3, client-1, client-2, client-3.

We see jobs finding the baselines in correct order ending last configuration model-3 and client-3. After some random time, polling finds an old configuration and starts a new build.
By the design the new build i failed, as the configuration is not new and the build get no new baselines when building.

You will se failed jobs appearing and pollings logs like below. Build #11 is the first to fail, after finding no new baselines (though the polling log did).
Build #10 was success.
